efi Grub2 of Ubuntu 10.10 x64 fails to execute on qemu with -enable-kvm

I am trying to run Ubuntu 10.10 x64 on qemu with OVMF EFI BIOS. Everything is fresh off the tree. While I can boot into the Bootloader and the bootloader can boot into OS if I have disabled kvm using -no-kvm option when I start the VM.
The qemu system crashes with the following error if I enable kvm in the VM.
This is a pain, because without the kvm the installation and booting is really really slow. I tried to debug it from the EFI BIOS a little bit and it seems that the boot loader crashed with this exception immediately after it was started.
Other developers on OVMF and EDK2 development (EFI BIOS) have also pointed out that in order to use Ubuntu 10.10 with EFI, you have to disable kvm. This seems to be an issue.
If there are any pointers (or any other debug help you want from me) in order to help root cause the issue, that would be helpful. Also, I can drop into the EFI Shell and start the bootloader efi image manually, which results in the same crash. Can I pass some parameters to the boot loader image to get some more information about the crash or the boot loader progress before the crash?
I have downloaded the Grub2 sources and am trying to look into this issue. If someone has been able to reproduce the issue, do let me know.
